  1. mmc: queue: turn queue flags into bools

    linusw authored and storulf committed Feb 1, 2017
    Instead of masking and setting two bits in the "flags" field
    for the mmc_queue, just use two bools named "suspended" and
    "new_request".
    
    The masking and setting would likely have race conditions
    anyways, it is better to use a simple member like this.

  2. mmc: core: Move public functions from card.h to private headers

    storulf committed Jan 13, 2017
    A significant amount of functions and other definitions are available
    through the public mmc card.h header file. Let's slim down this public mmc
    interface, as to prevent users from abusing it, by moving some of the
    functions/definitions to private mmc header files.
    
    This change concentrates on moving the functions into private mmc headers,
    following changes may continue with additional clean-ups.

  4. mmc: core: Use kmalloc_array() in mmc_alloc_sg()

    elfring authored and storulf committed Jan 8, 2017
    * A multiplication for the size determination of a memory allocation
      indicated that an array data structure should be processed.
      Thus use the corresponding function "kmalloc_array".
    
      This issue was detected by using the Coccinelle software.
    
    * Replace the specification of a data structure by a pointer dereference
      to make the corresponding size determination a bit safer according to
      the Linux coding style convention.

    Pull another MMC update from Ulf Hansson:
     "Here's a second pull request for MMC for v4.10.
    
      As a matter of fact it's only one change that moves some mmc files
      around. I thought it was a good idea to get this into v4.10, as it
      gives us a nice and fresh base for v4.11. Summary:
    
      MMC core:
    
       - Move files from the card directory to the core directory to enable
         future clean-ups of the generic mmc header files and interfaces"

      mmc: block: Move files to core

  1. mmc: block: Move files to core

    storulf committed Dec 8, 2016
    Once upon a time it made sense to keep the mmc block device driver and its
    related code, in its own directory called card. Over time, more an more
    functions/structures have become shared through generic mmc header files,
    between the core and the card directory. In other words, the relationship
    between them has become closer.
    
    By sharing functions/structures via generic header files, it becomes easy
    for outside users to abuse them. In a way to avoid that from happen, let's
    move the files from card directory into the core directory, as it enables
    us to move definitions of functions/structures into mmc core specific
    header files.
    
    Note, this is only the first step in providing a cleaner mmc interface for
    outside users. Following changes will do the actual cleanup, as that is not
    part of this change.
